TECHNICAL FIELD

This disclosure relates generally to end user devices and more particularly to a system and method for alerting a user on the end user devices,

BACKGROUND

Electronic devices such as mobile phones, tablets, cameras have become an irreplaceable part of daily life of technologically sound people. Disadvantage of this engrossment into technological world is reduced awareness of users in public spaces, when the users are interacting with electronic devices. For instance, texting while crossing the road, taking a self-portrait photograph near a wild tiger, watching a video while climbing a hill etc. The lack of awareness of the user's surroundings, when they are interacting with the electronic devices, may be dangerous not only for the user, but also for the people in proximity to the user. In extreme situations, the lack of awareness may also lead to death.

One of the irresponsible interactions of the users with the electronic devices, that has become a major concern in recent years, is self-portrait photograph. Dangerous usage of self-portrait photographs, such as taking selfie at edge of a cliff, posing with a gun, taking selfie on a fast moving vehicle, taking selfie hi a funeral, public restroom etc., may lead to embarrassment, injuries or death. Hence, there arises a need for alerting the user of risks, while interacting with the electronic devices.

FIG. 1 illustrates an exemplary network environment 100 comprising an electronic device 102, in accordance with some embodiments of the present disclosure. As shown in FIG. 1, the electronic device 102 is communicatively coupled to a user 104, one or more sensors 106, an image database 108, an image capturing device 110 and a display device 112. Although, the one or more sensors 106, the image database 108, the image capturing device 110 and the display device 112 is shown external to the electronic device 102 in FIG. 1, it may be noted that in one implementation, the one or more sensors 106, the image database 108, the image capturing device 110 and the display device 112 may be present within the electronic device 102.

The electronic device 102 may be communicatively coupled to the image database 108, the image capturing device 110 and the display device 112 through a network. The network may be a wireless network, wired network or a combination thereof. The network can be implemented as one of the different types of networks, such as intranet, local area network (LAN), wide area network (WAN), the Internet, and such. The network may either be a dedicated network or a shared network, which represents an association of the different types of networks that use a variety of protocols, for example, Hypertext Transfer Protocol (HTTP), Transmission Control Protocol/Internet Protocol (TCP/IP), Wireless Application Protocol (WAP), etc., to communicate with each other. Further, the network may include a variety of network devices, including routers, bridges, servers, computing devices, storage devices, etc.

As shown in FIG. 1, the electronic device 102 comprises a processor 114, a memory 116 coupled to the processor 114 and interface(s) 118. The processor 114 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, and/or any devices that manipulate signals based on operational instructions. Among other capabilities, the processor 114 is configured to fetch and execute computer-readable instructions stored in the memory 116. The memory 116 can include any non-transitory computer-readable medium known in the art including, for example, volatile memory (e.g., RAM), and/or non-volatile memory (e.g., EPROM, flash memory, etc.).

The interface(s) 118 may include a variety of software and hardware interfaces, for example, a web interface, a graphical user interface, etc., allowing the electronic device 102 to interact with a user. Further, the interface(s) 118 may enable the electronic device 102 respectively to communicate with other computing devices. The interface(s) 118 can facilitate multiple communications within a wide variety of networks and protocol types, including wired networks, for example LAN, cable, etc., and wireless networks such as WLAN, cellular, or satellite. The interface(s) 118 may include one or more ports for connecting a number of devices to each other or to another server.

In one implementation, the electronic device 102 includes modules 120 and data 122. In one embodiment, the modules 120 and the data 122 may be stored within the memory 116. In one example, the modules 120, amongst other things, include routines, programs, objects, components, and data structures, which perform particular tasks or implement particular abstract datatypes.

In one implementation, the modules 120 include a determining module 124, a risk determining module 126 and an alerting module 128. In an example, the modules 120 may also comprise other modules 130. The other modules 130 may perform various miscellaneous functionalities of the electronic device 102. It will be appreciated that such aforementioned modules 120 may be represented as a single module or a combination of different modules.

In one example, the data 122 serves, among other things, as a repository for storing data fetched, processed, received and generated by one or more of the modules 120. In one implementation, the data 122 may include sensor data 132. In one embodiment, the data 122 may be stored in the memory 116 in the form of various data structures. In an example, the data 122 may also comprise other data 134 including temporary data and temporary files, generated by the modules 120 for performing the various functions of the electronic device 102.

In order to alert a user of risks, the electronic device 102 may receive one or more sensor data 132. Sensor data 132 may include location data, proximity data, luminance data, accelerometer data, gyroscope data, height from ground level, temperature, humidity and image data. In one embodiment, the location data may be determined using a Global Positioning System (GPS), the proximity data may be determined using proximity sensors such as inductive, capacitive, photoelectric, ultrasonic etc. In one embodiment, the luminance data may be identified using ambient light sensors, the accelerometer data may be extracted using accelerometers such as bulk micromachined capacitive, bulk micromachined piezoelectric resistive etc. and the gyroscope data may be extracted using gyroscopes such as ring laser and fiber optics gyroscopes, dynamically tuned gyroscopes etc. The height from ground level may be determined using pressure sensors such as gage, absolute or differential pressure sensors and the temperature may be determined using temperature sensors. The humidity may be determined using humidity sensors such as metal-paper coil type, hair tension hygrometers, psychrometer etc., and the image data may be determined using an image capturing device 110. The image data may comprise postures of the user 104, the number of people in the image etc.

After receiving the one or more sensor data 132, one or more environmental factors, a current activity of the user 104 (or user activity factor), one or more motion data of the electronic device 102 and one or more objects in proximity to the user 104 (or objects in proximity factor), may be determined from the one or more sensor data 132. The environmental factors may include height from ground level, posture of the user 104, location data, temperature, humidity or illumination. In one embodiment, the illumination may be extracted from the luminance data. In one embodiment, the environmental factors may be determined using ambient air temperature sensor, illuminance sensor, ambient air pressure sensor or ambient relative humidity sensor. The current activity of the user 104 may include running, walking, driving, biking or remaining still. In one embodiment, the current activity may be identified using accelerometer, temperature sensors, gyroscopes, pressure sensors and humidity sensors. In another embodiment, the current activity of the user 104 may be identified using an activity recognition Application Programming Interface (API).

The one or more motion data may include tilt, shake, rotation or swing. In one embodiment, motion data may be identified using geomagnetic field sensor, accelerometer or gyroscope sensor. In one embodiment, objects in proximity to the user 104 may include hills, valleys, vehicles, fire, water bodies, slippery surfaces, wild animals, safety notices or number of people. The objects in proximity to the user 104 may be determined using the image data from the image capturing device 110 and the proximity data from the proximity sensors.

In order to determine the objects in proximity to the user 104, initially, images captured by the image capturing device 110 is divided into several segments. Objects are then identified in each segment and then labelled. In one embodiment, the identification of objects is done using a multimodal recurrent neural network (MRNN). The MRNN model consists of a deep recurrent neural network for sentences and a deep convolutional network for images. These two networks interact with each other in a multimodal layer. The MRNN is trained using several images that are extracted from the image database 108. The image database 108 comprise a plurality of historic images that were found to be either dangerous or safe, depending on the effect the user 104 had while interacting with the electronic device 102. The MRNN essentially enables conversion of an image into a sentence with context. This sentence with contexts may be used to identify the objects in proximity to the user 104. In one embodiment, natural language understanding techniques may be employed for comprehending safety notices that are available in the images.

After determining the environmental factors, the user activity factors, the motion data of the electronic device 102 and the objects in proximity factor, an initial degree of safety for each of the environmental factors, the user activity factors, the motion data and the objects in proximity factors, is generated. The initial degree of safety is indicative of scores assigned to each factor such as environmental factors, motion data etc. and may include safe, unsafe or care. If possibility of danger is above a first threshold, then the initial degree of safety may be unsafe. If the possibility of danger is above a second threshold (where the value of the second threshold is less than the value of the first threshold), but below the first threshold, then the initial degree of safety may be care. When the possibility of danger is below the second threshold, the initial degree of safety may be safe.

The first threshold and the second threshold may be dynamically adaptive thresholds. The thresholds may be dynamically adaptive based on the objects in proximity to the user 104. In one illustration, the image data and the proximity data may reveal that there is a forest in proximity to the user 104. The threshold for temperature is lowered since there is a risk of fire. This means that a lower degree of temperature may trigger the alert (unsafe) to the user 104 as compared to temperature threshold for a terrain without a forest in site. In another illustration, the terrain extracted from the image data may reveal that the area is a desert, then the threshold of the temperature needs to be increased, otherwise no user 104 will be able to message or take pictures in desert areas. In one embodiment, the user 104 may provide values for the first threshold and the second threshold via the interface 118.

In one illustration, the image data and the proximity data may reveal that even though the user 104 is inside a moving vehicle, the user 104 is not driving the vehicle. In the same illustration, the first and the second threshold for the corresponding current activity factor needs to be increased. This is because it is safe for the user 104 in the passenger seat to interact with the electronic device 102. In one illustration, the electronic device 102 may be in a moving train and the motion data may indicate constant shaking. This might not necessarily mean that care needs to be taken while interacting with the electronic device 102 in a train. Hence, the first threshold and the second threshold needs to be increased in this illustration.

After generating the initial degree of safety, the aggregate degree of safety is generated. The aggregate degree of safety may include safe, unsafe or care. The aggregate degree of safety is based on the initial degree of safety and one or more predefined rules. Initially, scores are assigned to each of the environmental factors, the user activity factors, the motion data and the objects in proximity factors. The scores are assigned based on the dynamically adaptive thresholds. The assigned scores are indicative of the initial degree of safety. After assigning the scores, maximum value of the assigned scores may be determined from each of the factors.

The maximum values of the factors along with the predefined rules may be used to generate the aggregate degree of safety. In one embodiment, the predefined rules may be that if the maximum value of user activity factor, objects in proximity factor and the environmental factor indicates that it is unsafe, then the aggregate degree of safety is unsafe. In one embodiment, if the maximum value of any two factors from the motion data, the objects in proximity factor, the environmental factor and the user activity is care, then the aggregate degree of safety is care. In one embodiment, if the maximum value of the motion data, alone, indicates that the motion data is unsafe, then the aggregate degree of safety is care.

Table. 1 is an exemplary table that shows each of the environmental factors and the scores that are assigned to it, may indicate safe, ‘2’ may indicate care and ‘3’ may indicate unsafe. When the maximum value of the environmental factor indicates ‘3’, that is unsafe, then the output corresponding to the environmental factor may be considered as unsafe. Similarly, when the maximum value of the environmental factor indicates ‘2’, then the output corresponding to the environmental factor may be considered as care and when the maximum value of the environmental factor indicates ‘1’, then the output corresponding to the environmental factor may be considered as safe. The output corresponding to the environmental factor may be used to generate the aggregate degree of safety.

TABLE 2 Activities Initial degree of safety Remaining Still Safe Walking Care Running Unsafe In a vehicle Unsafe Biking Unsafe

Table. 2 is an exemplary table that shows each of the user activity factors and the corresponding initial degree of safety. This table is for representative purpose only. The initial degree of safety corresponding to each of the user activity factors may also depend on the dynamically adaptive thresholds. For instance, there might be situations where it is perfectly safe to interact with the electronic device 102, when the user 104 is in a vehicle and is not driving.

TABLE 3 Motion data Max Tilt Shake Rotation Swing value Output 3 2 2 2 3 Unsafe 2 3 1 1 3 Unsafe 2 2 2 2 2 Care 1 1 1 1 1 Safe

Table. 3 is an exemplary table that indicates each of the motion data of the electronic device 102 and the scores that are assigned to them. If the maximum value of the motion data indicates ‘3’, then the output corresponding to the motion data is considered as unsafe. When the maximum value of the motion data indicates ‘2’, then the output corresponding to the motion data is considered as care. When the maximum value of the motion data indicates ‘1’, then the output corresponding to the motion data is considered as safe. The output corresponding to the motion data may also be used to generate the aggregate degree of safety.

The output corresponding to the environmental factor, the user activity factor, the motion data and the objects in proximity factor may be used to determine the aggregate degree of safety. In one embodiment, the aggregate degree of safety may be determined from the output corresponding to the environmental factors, the user activity factors, the motion data and the objects in proximity factor, along with the predefined rules. In one embodiment, the predefined rules may be that if the maximum value of the user activity factor, the objects in proximity factor and the environmental factor indicates that it is unsafe, then the aggregate degree of safety is unsafe. In one embodiment, if the maximum value of any two factors from the motion data, the objects in proximity factor, the environmental factor and the user activity factor is care, then the aggregate degree of safety is care. In one embodiment, if the maximum value of the motion data, alone, indicates that the motion data is unsafe, then the aggregate degree of safety is care.

In another embodiment, the aggregate degree of safety may be generated by initially assigning weightages to the environmental factor, the user activity factor, the motion data and the objects in proximity factor. The weightages may depend on the objects in proximity to the user 104. After assigning weightages, the maximum value of the environmental factor, the user activity factor, the motion data and the objects in proximity factor and the assigned weightages may be used to determine an aggregate index.

Aggregate index=ENV*ENV_(Wt)+UA*UA_(Wt)+MD*MD_(Wt)+OBJ*OBJ_(Wt),

wherein the ENV indicates the maximum value of the environmental factor, UA indicates the maximum value of the user activity factor, MD indicates the maximum value of the motion data and the OBJ indicates the maximum value of the objects hi proximity factor. ENV_(Wt) indicates the weightage assigned to the environmental factor, UA_(Wt) indicates the weightage assigned to the user activity factor, MD_(Wt) indicates the weightage assigned to the motion data and OBJ_(Wt) indicates the weightage assigned to the objects in proximity factor.

In one illustration, when the aggregate index is above a particular threshold, then the aggregate degree of safety may still be unsafe, even if the maximum value of all the factors indicates care. In one embodiment, the particular threshold may be provided by the user 104 via the interface 118. In another embodiment, the particular threshold may be determined using an artificial neural network. The input for the artificial neural network may be the maximum value of factors associated with the historical data and the effect, associated with the historical data, on the user 104 interacting with the electronic device 102. For instance, the effect may be whether an accident had occurred or not.

After generating the aggregate degree of safety, the user 104 is alerted of potential danger while interacting with the electronic device 102. The alert is based on the aggregate degree of safety. In one embodiment, alerts, such as textual alert, graphical alert, vibration alert may be used. In another embodiment, features like calling, texting, capturing images etc. may be disabled after a predefined time interval from the time of alerting the user 104, depending on the severity of the aggregate degree of safety. This disabling feature ensures the safety of the user 104 even if the user 104 is still willing to take the risk of interacting with the electronic device 102, even after viewing the alert in the display device 112.

In one illustration, features maybe disabled when the aggregate degree of safety indicates unsafe. In the same illustration, when the aggregate degree of safety indicates safe or care, then the user 104 may be alerted using textual alert, graphical alert or vibration alert. The textual or graphical alert may be displayed using the display device 112.

In one illustration, the user 104 may be in a hilly area with a slippery surface. The image capturing device 110 of the electronic device 102 will automatically be turned on.

TABLE 4 Environmental Factors orien- Height tation location temp Humidity illumination Max o/p 1 1 1 2 1 1 2 Care

Table. 4 shows the scores that may be assigned to each of the environmental factors. The temperature might be low in hilly areas and hence the score assigned may be ‘2’. This makes the output of the environmental factor as care.

TABLE 5 Motion data Tilt Shake Rotation Swing Max O/P 1 2 2 2 2 Care

Table. 5 shows the scores that may be assigned to each of the motion data. When the user 104 is climbing a hilly area with slippery surfaces, then the electronic device might shake, rotate and swing. Hence the scores assigned to shake, rotation and swing may be ‘2’, thus making the output of the motion data as care.

TABLE 6 User activity factor Remaining In a still Walking Running vehicle Biking Max O/P 0 2 0 0 0 2 Care

Table. 6 shows the scores that may be assigned to each of the user activity factors. All sub-factors except walking will be assigned 0 since the user 104 is only climbing the hill by walking. The score that is assigned to waking may be 2, which makes the output of the user activity factor, as care,

TABLE 7 Objects in proximity factor Slippery Safety No. of Wild Hills Valleys Surface notices people animals Max O/P 3 3 3 0 1 0 3 Unsafe

Table. 7 shows the scores that may be assigned to each of the objects in proximity factors. In the illustration, the images captured by the image capturing device 110 may not reveal the presence of wild animals or safety notices. Hence the scores assigned to the wild animals and safety notices may be 0. Presence of hills, valleys, slippery surfaces may be identified from the images and the scores assigned to them may be ‘3’. This makes the output of the objects in proximity factor as unsafe.

In the same illustration, the outputs associated with the factors are analyzed to determine the aggregate degree of safety. The outputs associated with the environmental factor, the motion data, the user activity factor is care. The output associated with the objects in proximity factor is unsafe. When we apply the predefined rules, the aggregate degree of safety becomes unsafe since one of the outputs are unsafe.

FIG. 2 is a flow diagram illustrating a method of alerting a user 104 of risks. With reference to FIG. 2, one or more sensor data 132 may be received at step 202. Sensor data 132 may include location data, proximity data, luminance data, accelerometer data, gyroscope data, height from ground level, temperature, humidity and image data. In one embodiment, the location data may be determined using a Global Positioning System (GPS), the proximity data may be determined using proximity sensors such as inductive, capacitive, photoelectric, ultrasonic etc. In one embodiment, the luminance data may be identified using ambient light sensors, the accelerometer data may be extracted using accelerometers such as bulk micromachined capacitive, bulk micromachined piezoelectric resistive etc. and the gyroscope data may be extracted using gyroscopes such as ring laser and fiber optics gyroscopes, dynamically tuned gyroscopes etc. The height from ground level may be determined using pressure sensors such as gage, absolute or differential pressure sensors and the temperature may be determined using temperature sensors. The humidity may be determined using humidity sensors such as metal-paper coil type, hair tension hygrometers, psychrometer etc., and the image data may be determined using an image capturing device 110. The image data may comprise postures of the user 104, the number of people in the image etc.

After receiving the one or more sensor data 132, one or more environmental factors, a current activity of the user 104 (or user activity factor), one or more motion data of the electronic device 102 and one or more objects in proximity to the user 104 (or objects in proximity factor), may be determined from the one or more sensor data 132, at step 204. The environmental factors may include height from ground level, posture of the user 104, location data, temperature, humidity or illumination. In one embodiment, the illumination may be extracted from the luminance data. In one embodiment, the environmental factors may be determined using ambient air temperature sensor, illuminance sensor, ambient air pressure sensor or ambient relative humidity sensor. The current activity of the user 104 may include running, walking, driving, biking or remaining still. In one embodiment, the current activity may be identified using accelerometer, temperature sensors, gyroscopes, pressure sensors and humidity sensors. In another embodiment, the current activity of the user 104 may be identified using an activity recognition Application Programming Interface (API).

The one or more motion data may include tilt, shake, rotation or swing. In one embodiment, motion data may be identified using geomagnetic field sensor, accelerometer or gyroscope sensor. In one embodiment, objects in proximity to the user 104 may include hills, valleys, vehicles, fire, water bodies, slippery surfaces, wild animals, safety notices or number of people. The objects in proximity to the user 104 may be determined using the image data from the image capturing device 110 and the proximity data from the proximity sensors.

In order to determine the objects in proximity to the user 104, initially, images captured by the image capturing device 110 is divided into several segments. Objects are then identified in each segment and then labelled. In one embodiment, the identification of objects is done using a multimodal recurrent neural network (MRNN). The MRNN model consists of a deep recurrent neural network for sentences and a deep convolutional network for images. These two networks interact with each other in a multimodal layer. The MRNN is trained using several images that are extracted from the image database 108. The image database 108 comprises a plurality of historic images that were found to be either dangerous or safe, depending on the effect on the user 104 while interacting with the electronic device 102. The MRNN essentially enables conversion of an image into a sentence with contexts. This sentence with contexts may be used to identify the objects in proximity to the user 104. In one embodiment, natural language understanding techniques may be employed for comprehending safety notices that are available in images.

After determining the environmental factors, the user activity factor, the motion data of the electronic device 102 and the objects in proximity factor, an initial degree of safety for each of the environmental factors, the user activity factor, the motion data and the objects in proximity factor, is generated, at step 206. The initial degree of safety is indicative of scores assigned to each factor such as environmental factors, motion data etc. and may include safe, unsafe or care. If possibility of danger is above a first threshold, then the initial degree of safety may be unsafe. If the possibility of danger is above a second threshold (where the value of the second threshold is less than the value of the first threshold), but below the first threshold, then the initial degree of safety may be care. When the possibility of danger is below the second threshold, the initial degree of safety may be safe.

The first threshold and the second threshold may be dynamically adaptive thresholds. The thresholds may be dynamically adaptive based on the objects in proximity to the user 104. In one illustration, the image data and the proximity data may reveal that there is a forest in proximity to the user 104. The threshold for temperature is lowered since there is a risk of fire. This means that a lower degree of temperature may trigger the alert (unsafe) to the user 104 as compared to temperature threshold for a terrain without a forest in site. In another illustration, the terrain extracted from the image data may reveal that the area is a desert, then the threshold of the temperature needs to be increased, otherwise no user 104 will ever be able to message or take pictures in desert areas. In one embodiment, the user 104 may provide values for the first threshold and the second threshold via the interface 118.

After generating the initial degree of safety, the aggregate degree of safety is generated, at step 208. The aggregate degree of safety may include safe, unsafe or care. The aggregate degree of safety is based on the initial degree of safety and one or more pre-defined rules. Initially, scores are assigned to each of the environmental factors, the user activity factors, the motion data and the objects in proximity factors. The scores are assigned based on the dynamically adaptive thresholds. The assigned scores are indicative of the initial degree of safety. After assigning the scores, maximum value of the assigned scores may be determined from each of the factors.

The maximum values of the factors along with the predefined rules may be used to generate the aggregate degree of safety. In one embodiment, the predefined rules may be that if the maximum value of user activity factor, objects in proximity factor and the environmental factor indicates that it is unsafe, then the aggregate degree of safety is unsafe. In one embodiment, if the maximum value of any two factors from the motion data, the objects in proximity factor, the environmental factor and the user activity factor is care, then the aggregate degree of safety is care. In one embodiment, if the maximum value of the motion data, alone, indicates that the motion data is unsafe, then the aggregate degree of safety is care.

The output corresponding to the environmental factor, the user activity factor, the motion data and the objects in proximity factor and the predefined rules may be used to determine the aggregate degree of safety. In one embodiment, the aggregate degree of safety may be determined from the output corresponding to the environmental factors, the user activity factors, the motion data and the objects in proximity factor, along with the predefined rules.

In another embodiment, the aggregate degree of safety may be generated by initially assigning weightages to the environmental factor, the user activity factor, the motion data and the objects in proximity factor. The weightages may depend on the objects in proximity to the user 104. After assigning weightages, the maximum value of the environmental factor, the user activity factor, the motion data and the objects in proximity factor and the assigned weightages may be used to determine an aggregate index.

Aggregate index=ENV*ENV_(Wt)+UA*UA_(Wt)+MD*MD_(Wt)+OBJ*OBJ_(Wt).

wherein the ENV indicates the maximum value of the environmental factor, UA indicates the maximum value of the user activity factor, MD indicates the maximum value of the motion data and the OBJ indicates the maximum value of the objects in proximity factor. ENV_(Wt) indicates the weightage assigned to the environmental factor, UA_(Wt) indicates the weightage assigned to the user activity factor, MD_(Wt) indicates the weightage assigned to the motion data and OBJ_(Wt) indicates the weightage assigned to the objects in proximity factor.

In one illustration, when the aggregate index is above a particular threshold, then the aggregate degree of safety may still be unsafe, even if the maximum value of all the factors indicates care. In one embodiment, the particular threshold may be provided by the user 104 via the interface 118. In another embodiment, the particular threshold may be determined using an artificial neural network. The input for the artificial neural network may be the maximum value of factors associated with the historical data and the effect, associated with the historical data, on the user 104 interacting with the electronic device 102. For instance, the effect may be whether an accident had occurred or not.

After generating the aggregate degree of safety, the user 104 is alerted of potential danger while interacting with the electronic device 102, at step 210. The alert is based on the aggregate degree of safety. In one embodiment, alerts, such as textual alert, graphical alert, vibration alert may be used. In another embodiment, features like calling, texting, capturing images etc. may be disabled after a predefined time interval from the time of alerting, depending on the severity of the aggregate degree of safety. This disabling feature ensures the safety of the user 104 even if the user 104 is still willing to take the risk of interacting with the electronic device 102, even after viewing the alert in the display device 112.
